On Friday we discussed the mid-term review of the ongoing feasibility study for a huge future circular collider at CERN. I should write more about that whole thing soon, but for now, here’s a link to me and Tara Shears talking about it with Justin Webb on the BBC Radio 4’s today programme. (About 07:50, 5 February, just after thought for the day.)

Hopefully this link works: https://www.bbc.co.uk/programmes/b006qj9z
